Dubberke | May 31, 1994 |
A snap fastener for securing shoe laces comprises two openings disposed diametrically to each other through which the shoe laces are passed. The openings extend longitudinally through the snap fastener when the latter is opened. An inner sleeve is in a larger outer sleeve such that it is longitudinally movable relative thereto. The inner sleeve accommodates an inner ring. When the pressure is exerted on the outer sleeve, the ring is made to rotate as the longitudinal movement is converted into a horizontal circular movement so that the shoe laces are immovably clamped by the snap fastener.
